* At Qnom  pressure drop will be approximately 1 bar (14 psi) for H20. Sensors can be operated at higher flow rates but pressure drop will be higher. Maximum recommended velocity (liquid) through the sensor is 15 m/s. Beyond this point, cavitation may occur. Qmin is the recommended lowest flow rate. Sensors will measure flow rates lower than Qmin, but uncertainty may increase beyond 0.5% of rate.

These flow rate and pressure drop statements relate to standard pressure tube sensor versions. Models with higher pressure ratings have increased wall thickness and will have higher pressure drops and lower Qnom values.
